What is Product Design: A Comprehensive Guide

Product design is the strategic process of crafting solutions for user needs that achieve business goals. In the digital world, this means designing intuitive apps, websites, and SaaS platforms.

As a full-service digital product agency, Big Human takes a user-first, collaborative approach to product design. From reimagining iconic institutions like Rockefeller Center to building digital-first startups from the ground up, we’ve designed products that scale and stand out.

Let’s break down what digital product design is, and how interface design, development, and strategy work together to make it happen.

What Is Digital Product Design?

Digital product design shapes how people interact with apps, websites, and software. It’s about what a product looks like, how it works, how it feels — and most importantly, how it solves problems for users.

Great product design exists at the crossroads between form and function. It blends research, interface design, and product strategy into a single user experience that feels intuitive, purposeful, and scalable. Every screen, flow, and feature is intentional.

At Big Human, design is a core business tool, translating business goals into meaningful experiences that drive growth.

At a Glance: What Makes Great Product Design?

• Real product design starts with real problems. The best solutions are rooted in user insights, not assumptions.

• Great design isn’t rigid. It adapts as your business and users evolve.

• Thoughtful interface design doesn’t confuse or frustrate users; it guides them.

• Every decision, from layout to microcopy, should achieve a clear business goal.

The Digital Product Design Process

Digital product design doesn’t have to be a straight line, and most businesses (or product design agencies) approach it a little differently. At Big Human, we follow a collaborative, iterative process that balances user insight with technical feasibility and business strategy. 

Generally, product designers work through a few key stages, starting with early research and strategy. Rapid prototyping and early testing follows, then full-scale development, A/B testing, and finally, launch, and continued optimization. Each phase should build toward a product that’s intuitive, scalable, and built to last.

Understand the User and Market Through Research & Strategy

Good product design starts with a deep understanding of your users. User research helps figure out who they are, what they need, and where your product fits into their lives.

This phase is about diving in deep with market analysis, user interviews, competitive audits, and business alignment. The goal is to uncover user problems worth solving, then shape a product vision that’s both user friendly and commercially viable (along with a strategy to guide it).

Our go-to roadmap: Treat research, brainstorming sessions, and strategy as the foundation of good product design. From there, combine qualitative insights with business objectives to define clear objectives, personas, and early hypotheses.

Ideate & Prototype

Once user and market research defines the opportunity, ideation turns insights into tangible design principles and real-world application. Here, brainstorming meets problem solving: drafting concepts, sketching flows, and otherwise exploring how users might interact with your product.

Rapid prototyping can play a vital role in this stage. Prototyping tools like low-fidelity wireframes and mockups let teams test assumptions, visualize user journey maps, surface pain points, and gather stakeholder feedback before investing in full development and further decision making. 

Clarity is the goal — not perfection. Prototyping is about pressure-testing product ideas to find what works in practical scenarios. Gathering user feedback validates stronger concepts before full-scale development begins.

Design the Experience & Interface

Now that you have a proven concept, the next step is designing how the product looks and works. Map out the structure and flow of the interface, ensuring every interaction feels smooth and intuitive. Then bring the product to life visually, shaping its layout, typography, motion, color palette and other graphic design elements.

Together, experience and interface design (formerly UX design and UI design) define the feel of your product and guide users toward their goals. 

Our design teams craft their work with a purpose. We combine interaction design, accessibility standards, and brand strategy to build a product experience with a visual design that’s beautiful and original — as well as clear, inclusive, and effective for the end user.

Enter Full-Scale Product Development

Once the design system and experience are ready, it’s time to bring the product to life. Development turns designs into working software — coded, tested, and built for scale. Front-end and back-end engineers collaborate closely with designers and strategists to ensure each interaction works correctly (and looks good). 

Seamless navigation, real-time data, thoughtful information architecture — it all comes together here.

Test, Launch, & Evolve Through Iteration

Real-world user testing should optimize any remaining wrinkles. Before and after launch, usability testing and QA ensure that the new product works as expected. 

The “final product” at launch is (ideally) not the end of the process. Every new click, swipe, or other user behavior provides valuable insight. Successful products are built to evolve, which means improving performance, expanding features, and adapting to shifting customer needs over time.

A Collaborative, Full-Service Approach to Product Design

At Big Human, product design isn’t siloed. We bring strategy, design, and engineering together from the start. This cross-functional approach ensures that each decision, from design ideas to back-end logic, achieves business goals.

We work in tandem with your product team to make sure each product is worthy of investment and built to evolve. Whether we’re launching a startup’s first MVP or modernizing a legacy system, we design with intent and back it with execution.

Product Design Case Study: A Multi-Purpose Website for Netflix

Netflix tapped Big Human to unify its fragmented web presence. Our goal? A single digital product that could support media inquiries, corporate storytelling, and internal workflows across global teams.

We designed and built a dynamic website for Netflix that functions as both a corporate home and a media center, complete with blog posts, news updates, accessibility-friendly content, and more. Netflix is a global, multilingual brand, so the site needed to be scalable and secure, and integrated with Netflix’s internal tools and data sources.

The design solution: From user interface design to backend development, we optimized every element to support performance, usability, and storytelling. This gave Netflix a centralized, future-proof platform that works for every audience.
